Automobile exhaust pipe, also called automobile exhaust hose, is installed between the engine exhaust pipe branch pipe and muffler at the rear of the automobile. The exhaust pipe is divided into hot end and cold end, the part near the engine is the hot end, and the part near the rear of the car is the cold end. The material of automobile exhaust pipe is generally stainless steel, and its main function is to reduce vibration and noise. When using a car at ordinary times, be sure to avoid water from the muffler. If water enters accidentally, you need to start the engine, idle the car for about 10 minutes, and drain the accumulated water inside.
